O le alualu i luma talu ai nei i le mamanu ma le faʻaogaina o mea faʻapipiʻi uta ituaiga ratchet ua puʻeina ai le mafaufau o pisinisi faʻatau ma felauaiga. Ua lauiloa i lo latou maufaatuatuaina ma le tumau, o nei fusifusia ua faia ni suiga taua e fetaui ma manaoga o pisinisi.
O lo'o tu'ufa'atasia e le au gaosi mea fou i totonu o latoufa'amau fa'amomoli uta ituaiga, e pei o le faʻaleleia o le lever mechanisms ma mea e sili atu ona malosi, e faʻaleleia ai le malosi faʻamalosi ma le atoatoa lelei. O nei fa'aleleia e le gata ina fa'aoga lelei ai mea fa'apipi'i i le fa'amauina o uta ae e saofagā fo'i i le fa'aleleia atili o le saogalemu i le taimi o felauaiga.
E le gata i lea, o loʻo molimauina e le alamanuia le faʻatupulaia o aga agaʻi i faʻasalalauga ifa'amau fa'amomoli uta ituaiga. O le tele o tagata gaosi oloa o loʻo ofoina atu ni fofo faʻapitoa e faʻafetaui ai manaʻoga faʻapitoa a tagata faʻatau, faʻamautinoa o loʻo fetaui lelei mea faʻapipiʻi ma ituaiga eseese o uta ma mea tau felauaiga.
Aʻo faʻaauau pea le faʻatupulaia o pisinisi faʻapitoa, o le manaʻoga mo tulaga maualugafa'amau fa'amomoli uta ituaigaua faamoemoe e tulai mai. Faatasi ai ma nei faʻaleleia fou, o loʻo sauni le au gaosi e faʻafetaui le faʻateleina o manaʻoga aʻo tausisia la latou tautinoga i le saogalemu ma le lelei.
Fa'alogo mo nisi fa'amatalaga i mea fou o atina'e i le ituaiga ratchet load binder technology ma pe fa'afefea ona latou fa'atulagaina le lumana'i o pisinisi fa'atau.
